| N2, N3, N4 Small Inclinometers for inclination measurement in the ranges of ±10, ±30 and ±70 degrees. |
Features
Description
The N2, N3 and N4
are capacitive, liquid based inclinometers with integrated sensor
electronics. They are manufactured with an analog DC output. The
sensor electronics require only minimal power and are in
conjunction with the capacitive primary transformer characterized
by high accuracy, a high signal-to-noise ratio and high long-term
stability.
The measurement technique enables a linear relationship between
the angle to be measured and the output signal. The determined
angle is independent of the local gravitational acceleration,
that means that no matter where the measurement is being taken,
whether in Europe, Australia, on Mount Everest or on the moon,
the inclination will be measured correctly anywhere.
Application
The inclinometers
N2, N3 and N4 are suitable for applications requiring a small,
light sensor for measurement of relatively large inclinations.
Typical areas of application include measuring instruments and
inspection systems, vehicles, automation and safety engineering,
scientific devices, medical and communications equipment as well
as navigational systems.
